Heat a grill or grill pan over medium-high. Brush with the oil. When hot, add the apricots, and sprinkle evenly with 1/8 tsp. of the salt. Grill for about 4 minutes. Flip and sprinkle with another 1/8 tsp. of the salt. Grill for another 4-6 minutes, until the apricots are tender and feature grill marks. Brush the apricots with 1 teaspoon of the agave nectar.
